What is the World Wide Web? And How Does It Work? - Two Good Explanations

Even though they use it everyday many of our students don't understand how the World Wide Web works. A recently released TED-Ed lesson tackles the topic of how the Web works. In What is the World Wide Web? students can learn about the origins of the Web, its evolution, and how we can contribute to the Web. The lesson includes eight review questions for students to try after watching the video. The video is embedded below.


Another good explanation of how the Web works is found in the Common Craft library of videos. Through the World Wide Web Explained by Common Craft students can learn about how computers are connected and the role of a web browser in displaying the information we see on our monitors. That video is embedded below.

A Map of the Cables Connecting the World

TeleGeography has produced a couple of interesting maps of the telecommunication cables that cross under oceans and seas. The interactive Submarine Cable map allows you to click on various points and lines to see the locations that they connect. The map also shows you who owns the lines depicted.

A poster (infographic) version of the Submarine Cable map is available too. The poster version includes a timeline of cables connected between 1997 and 2012.

Applications for Education
Students today grow up just assuming that the Internet connects everyone, but they probably don't think about how that actually happens. These maps could be a nice way to show students how much cable it takes to connect us. An extension of this would be to have students try to calculate or research how many miles of cable are under an ocean or sea.

H/T to Cool Infographics.

Stop, Think, Connect - Web Safety Resources from Microsoft

Thanks to Lee Kolbert I learned about Microsoft's Safety and Security Center. The Safety and Security Center contains many videos, PDFs, and PowerPoint presentations for learning about and teaching computer and web safety. The PDFs in are intended to printed as brochures for distribution. The videos can be embedded into your blog or website. The video section is organized into three sections; family safety, data protection, and computer protection. Below I've embedded the video, Stop, Think, Connect.

Excellent Free Ebook - How the Internet Works

So you and your students use the Internet everyday, but are you fluent in its language? Perhaps you've found yourself listening to a "techy" conversation where the terms IP, DNS, or PHP were being used and you wanted to know what those terms mean. What is an IP address? What is a DNS record? And just who is in charge of the Internet? Get answers to those questions and many more in Make Use Of's free ebook How the Internet Works.

Where Will Kids Put the Internet in the World?

Read Write Web and Latitude recently conducted a survey of children in which they asked the kids to share the things they think computers and the Internet should do. As you might expect some of the responses were very imaginative. I look at the results of the survey as a preview of what computers and the Internet will do in the next decade or two. If you don't want to read the reports here and here, at least watch the video below summarizing some of the students' responses.

How the Web Works - A Slideshow from the BBC

The BBC is currently offering two interesting resources about the Internet. Mapping the Growth of the Internet is an interactive map that provides a visualization of the growth of the Internet around the world since 1998. How the Web Works is a fourteen slide slideshow that explains how the information you see displayed on website on your computer gets there. How the Web Works provides clear visuals and helpful captions where necessary.

Hat tip to Mashable for the link to Mapping the Growth of the Internet.

Applications for Education
How the Web Works could be a good resource for computer science teachers and anyone else needing to provide an explanation of the web to students.

Dealing With Data Rot - From CBS

One of my favorite weekend television programs is CBS Sunday Morning. Yesterday, they ran a David Pogue segment about data rot. Data rot is what happens when your data is stored in a software format that cannot be displayed any longer because the hardware has been replaced. Every year I see an example or two of this with some of the veteran teachers in my school who have documents on floppy disks or in an old Mac format. In fact, the teacher who shares the workspace next to me has a stack of old IBM floppy disks (the kind with hole in the middle) that he refuses to get rid of.

Dealing With Data Rot is embedded below.


Applications for Education
There is a lesson in this video for all of us and it's, back up your data in a modern format. Whether it's personal photos or a simply fantastic lesson plan that you don't want to lose, moving your data to a modern format before it's too late is a good idea. The video also provides a good, short lesson on the development of computer technology over the last 40 years.

A good video to complement the one above is The History of the Internet.

History of Apple and the Internet

This year marks the 25th anniversary of the first Macintosh computers hitting the market. CNET has a good slideshow documenting the development of the Mac over the last 25 years. Two weeks ago I posted a video that explains the history of the Internet which you can view here or in the embedded video below.

Applications for Education
If you're a computer science teacher the CNET slideshow combined with the history of the Internet video could make a nice, short history lesson for your students.

Tools for Refining Internet Searches


Search The Tail is a great tool for refining the results of a Google search. If you're not finding the results you want or finding too many results, Search The Tail helps you refine and revise your search terms.













Application for Educators
Search the Tail can be used to help students find the results they need for a research assignment. Simply "Googling" the Great Wall of China will yield 5.62 million results and not give the student much of a clue about how to refine and narrow the search. Searching the same phrase on Search The Tail will give the student a list of results in one column and in a second column Search The Tail provides a list of terms to revise and narrow the search. Look the image to the left for an illustration of the results page on Search The Tail.
